CIGARETTE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 588,909, dated August 24, 189'?.

Application led March 25, 1896.

To all whom t may concern: j

Be it known that I, GEORGE H. HILGART- NER, a citizen of the United States, residing A' at Richmond, in the county of Henrico and State of Virginia, have invented certain new and useful Improvements in Cigarette-Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has relation to cigarette-machines, and morev particularly to that class wherein the filler is first picked and suitably prepared, then slightly pressed and cut into proper lengths and fed to the rolling-table, and the paper cut into suitable lengths with the requisite amount of paste applied to one edge thereof, then wrapped around the filler so that its edges are united and the formed cigarette delivered to the cutter, which trims its ends to the proper length and the finished cigarette delivered to the packers, the operation from beginning to end being accomplished automatically, as above described.

To these ends thel'novelty consists vin the construction, combination, and arrangement of the several parts cooperating to this common end, as will be hereinafter more fully described, and particularly pointed out in the claims. Y

In the accompanying drawings the same iigures and letters of reference indicate the same parts of the invention.

In the drawings, Figure lis a side elevation of my improved cigarette-making machine, viewed from the left-hand side thereof. Fig. 2 is a similar view taken from the right-hand side. Fig. 3 is a longitudinal central sectional elevation of the same. Fig. 4 is a top plan view. Fig`.`5is atop plan view on theline A A of Fig. 7. Fig. C is a top plan view of the endless-chain carriage. Fig. 6 is a side view of the same. Fig. 7 is a rear end view of the 1n achine; Fig. Sis an enlarged detail view ofthe oigarette-trimmin g device. Fig. 9 is another view of the same, showing the finished cigarette in the act of being discharged upon the endless carryin g-chain.

Fig. 26 lis an enlarged plan View of the paperfeeding, tension, and pastingdevices. Fig. 27 is a side elevation of the feed-rolls detached from the machine, and Fig. 28 is a section on the line C C of Fig. 27. A

The construction of my invention may be described as follows:

The cast metal sides 2 and 3 and the bed- .plate -l constitute the frame offthe machine,

endless belt 10, provided at suitable intervals with divisional strips or cross-bars 12, passes obliquely upward over a small roller 13,

IOO

thence obliq nel y dow n ward and forward over a roller 14, thence rearward along the bedplate 4, around a return-roller 15, thence forward between two feed-rollers 1G and 17 to the first roller f). The journals ot the roller 1h' are mounted in fixed bearings 1S in the depending brackets 1li, bolted underneath the bed-plate 4, and the journals of the lower roller 17 are mounted in adjustable bearings 20, sliding in guideways in said arms 19. These bearings :0 rest upon springs 21, which, through the medium of the roller 17, press the endless belt 10 against the roller 1G, the tension of the spring being regulated by thumb-screws 22. A `gear on the outside of the shaft ot' the roller 1U drives itin the direction of thearrow, and it will thus be seen that a continuousmotion inthe direction indicated by the arrows is imparted to the endless belt 10.

Mounted in the upper part ofthe side pieces 2 and 3, between them and above the endless belt 10, is a roller 23, driven by a sprocketwheel 23, connected by a sprocket-chain 232, driven by a sprocket-wheel on the shaft of the picker-cylinder 31 on the outside of the frame, and back of said roller is similarly mounted a smaller roller 24, and upon these rollers 24 is secured an endless belt 25, continuously driven by the roller 23 in the direction of the arrows, and the lower face ol the endless belt 25 is set at an angle or incline with reference to the endless belt lO, so that the discharge-opening between the rollers 15 and 24 will be contracted or narrower than the receiving-point between the roller 23 and the endless belt at the point inline-- diately beneath it.

The prepared cu t or loose tobacco is evenly spread in suitable quantities upon the endless belt 10 and between the dividing-strips 12 at the forward end of the machine. The tobacco is then conveyed by said belt 10 and discharged by gravity upon the picking-roller 26, whence it is caught by the picker-teeth 27 and carried under the solid pressure-roller 2S, having a plain surface, around which it is prevented from being thrown olf by the sheet-metal guard 2U. '1`he tobacco is then taken olf of the picking-roller 26 by the teeth 30 on the lower-picking roller 3l, which is in a different plane with the teeth 27 on the cylinder 2G, and the points of the teeth 3l) project beyond the periphery ofthe teeth 27 and pick the tobacco ot't from said teeth 27, carry it around below the lower portion ot' the guard 2S), and discharge it evenly upon the endless apron 10. The upper picking-roller 26 revolves in a comparatively slow motion in the direction ofthe arrow, while the lower picker-roller 31 revolves in the direction of the arrow much more rapidly, which eli'ectually picks or gins off the tobacco from the upper roller and discharges it evenly and regularly upon the endless belt, as above mentioned. The tobacco as thus received upon the endless belt 1 0 is conveyed rearward into the conveying-passage formed by the belts 10 and 25 and gradually compressed as it is carried back tothe discharge-opening between the rollers 15 and 24, where it is discharged upon the cutting-ott shelf 32, where its end is stopped by and it is further compressed against the face of the cutter-blade At a suitable moment the cutter-blade 33 is raised and the tobacco then continues its movement rearward until sufficient tobacco has been fed outward. At this moment the blade 33 descends, cuts ot'f the charge into the pocket 34, formed in the front end of the apron This cutter-blade 33 is rigidly secured in the outer ends 3b' of two verticallyreciprocating arms 37, located on each side of the base-plate 4 and between it and the inside of the sides 2 and 3, where they travel in two guide-brackets 38, adjustably secured tothe inside of said sides 2 and 3 by bolts 3f), (shown in Fig. 16,) so that the arms 37, and thereby the blade 33, may be adjusted with reference toits cutting edge. The lowerends of these arms 37 are hinged upon a transverse rod 40, which in turn is hinged by a pair of levers 41 to a rock-shaft 42, journaled in brackets 43, cast integral with the sides 2 and 3. The levers 41 are rigidly secured to either end of the rock-shaft 42, and between them and at approximately a right angle thereto is rigidly secured alever 44, to the upper end of which is connected one end of the forked connecting-rod 45, the forked end 46 of which encompasses the shaft 4S, and a cam 47 is rigidly secured upon and rotates with this main driving-shaft 4S, which is mounted in bearings 49 in the front end o1- the sides 2 and On the forked end 46 ol the rod 45 and on one side thereof' is journaled a friction-roller 50, against which the face of the cam 47 presses to raise the cutter-blade 33, and the roller 50 is held against the cam 47 in its rcturn movement, which is the downmtrd or cutting movement ot' the blade 33, by a spiral spring 5l, one end of which is secured to the lever 41 and the other end to a bolt 52, secured at a suitable point on one ol the sides 2, and the tension of this spring is so adjusted that while it will readily cut oli" the required charge of tobacco the motion ol the cutterblade will be arrested and injury to its edge prevented should small particles of metal, such as nails, tacks, or the like become accidently mixed in with the cut tobacco.

rlhe charge, being severed from the main body of the tobacco by the blade 33, lalls by gravity into the pocket 34 of the apron One end otthis apron 35 is clamped longitudinally in a divided rod 53, which is rigidly secured at its ends in thc lower ends of a pair of arms 54, rigidly secured to and depending from an oscillating shaft 55, jonrnaled in the sides 2 and 3, and similarly secured to said shafty 55 is an upwardly-projecting lever 5t, the free end ol' which is connected to a pitinan 57, the forked end of which engages a IOO IOS

IIO

cam 58, secured to the main shaft 48. yThis pitman and its operating-cam are similar in construction to the forked rod 45 and cam 48 above described, and consequently the de` scription of the one will answer for the other. The forward end of the apron 35 being secured to the divided rod 53, as before mentioned, the rod is now moved toward the cigarette-rollin g table, whereby sufficient slack is allowed to form the pocket 34. The apron then extends rearward, resting upon the ci garette-rolling table,passin g around the beveled end 60 thereof, and having its end secured to the under side thereof by a clamp Gl.

When the cam 58 operates to carry the divided rod 53 toward the cigarette-rolling table, the cigarette-rolling. head 73 closes the pocket in the apron with the charge of tobacco in it, and as soon as the cigarette-rolling head 73 enters on its journey on the cigarette-rolling table the divided rod 53, to which one end of the apron is attached, is moved away from the table by its cam 58 a sufficient distance to drawrthe apron snugly around the charge of tobacco, which it encompasses within the cigarette-rolling head 73, and the further movement of the said cigarette-rolling head rolls the charge of tobacco over andA over, ready to receive the wrapper, as will be hereinafter explained.

rlhe table 59 is adj ustably secured 'to a .bracket 62, so that its discharge end 60 will be slightly higher than its receivingend, (the drawings showing a somewhat exaggerated inclinatiom) whereby in the operation of forming the cigarette it is practically' rolled uphill. -The object of this is to retain the loose tobacco in the roll and prevent it from falling ahead of the roll by gravity and covering the paste end of the paper, thereby overcoming a very serious objection in that class of machines using asegnientaltable.

The bracket 62 is adjustably secured to lugs on the sides 2 and 3 by bolts 64', passing through vertical slots 65,and by means of this construction the table 59 may be raised or` lowered at will. This bracket 62 is provided with an integral guide 66, upon which a rolling-carriage 67 slides, the said carriage being reciprocated by a pitman 68, connected to a lever 69, the lower end of which is hinged to a shaft 70, secured between the sides 2 and 3,

and this lever is provided with a friction, roller 7l, which comes in Contact with a suitably-shaped cam 72, secured to the main shaft 48, which operates the carriage as follows: The parts being in the position shown in Fig. 2 and the charge of tobacco having fallen into the pocket in the apron, the cam 72 forces the carriage backward until its cigarette-rolling head 73 is about midway the length of the table 59, where it stops for a brief interval, as will be hereinafter explained. It then contin ues its movement tothe end 60 of the table, which is its limit in one direction. The cani 72 then releases it, and a spring 74, secured at One end to the lever 69 and at the other to the frame, restores the carriage at one continuous movement to its first position.

I will now proceed to describe the particular construction of the cigarette-rolling head 73 of the carriage 67.

Referring to Fig. 12, the cigarette-rolling head 73 is provided with an inverted semicircular recess 75, which is a trifle longer than the length of the cigarette, and 4at each end thereof in said cigarette-rolling headv is a plunger 7 6, pressed outwardly by a spiral spring 77, so that when the roll of tobacco is in the recess in the first step of the process of forming the cigarette the outer ends of the plungers will come into contact with the beveled ends 8O of the converging rails 79, force the plungers inwardly, as shown in Fig. 13, and compress and hold the ends of the roll of tobacco solid both before and after it has been wrapped. After the wrappin g and rolling operation has been completed and just before the cigarette is about to leave the rolling-table 59 the ends of the plungers 76 pass beyond the beveled ends 81 of the rails 79, leaving the cigarette free to be discharged when the cigarette-rolling head of the carriage has arrived at the end GO of the table. It will thus be seen that I. preserve the roll cylindrical and compact both in its body and at its ends, thereby making a firm solid roll in the wrapper.

After the cigarette has'been finished as lfar as above described and it has been discharged from the end 60 of the table it falls by gravity into a longitudinal semicircular recess 82 in the solid cylinder 83, and this cylinder is the exact length of a finished cigarette, and it is adjustably secured on a shaft 84, journaled in arms 85 on a bracket 86, secured to bracket 62 on the frame. One end of the shaft 84 is provided with a pinion 87 on the outside of the arm 85. Said cylinder 83 and pinion 87 are oscillated one-half of a revolution by a rack 88, reciprocating in a guide 89, secured IOO IIO

to the bracket 62, and the forward end of said l rack is connected to a cam 90 on the shaft 48 by a pitman 91, provided with a spring 92. The construction of said cam and pitman is the same as that described above for the cam 47 and pitman 45. The cylinder 83 is adjustably secured on its shaft 84 by a set-screw7 (not shown,) and its periphery may be provided with a series of semicircular recesses 82' of different sizes to correspond to the diameter of different-sized cigarettes.

Mounted upon the shaft 93 and driven by a small pulley 94 and belt 95 from a larger pulley on the main shaft 48 is a pair of cutter-disks 96, revolving in the direction of the arrows, and they are so adjusted that their peripheral cutting edges overlap the recess 82 and barely clear the ends of the cylinder 83, and at the same moment the cigarette is dropped into the recess 82 the rack 88 is operated by its cam 90 to semirotate the cylinder 83, which carries recess 82 containing the cigarette, around, when its ends come in con- IIS IZO
